The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour
Answer:
A: 8v+12b=360
V= van
B= Bus
B: Each van=9
Need to ride in vans:72
12 buses 24 in each bus that equals 288. 360-288=72
and if you need to know how many are in each van you divide 72 by the number of vans that would be 9 per van.
